In this video, we are going to cover evaluation metrics for regression models. You will learn about mean absolute error (MAE), mean square error (MSE), root mean square error (RMSE) and root mean square log error (RMSLE). You will learn how to calculate them and go though their differences.

Excellent! Simple and clear explaination
Thank you so much. MAE, MSE & RMSE has been a major blocker for me and you've cleared things up.
Excellent video so amazing thank you so much! - From a noob bioinformatics grad student
wow, I like your teaching approach
Excellent explanation. Thank you!
7:13, log(100) = 2 and log(130) = 2.11394335231
I think we have to take log of 101 and 131 that's why in formula Log(pi+1)log(ai+1) is available.
For rmsle to is the value closer to 0 better?
This is great! thanks a lot
great explanation
You are amazing.
Sir
All explanation is very nice. Easy to understand.
I have a question, should RMSE be less or greater than standard deviation? Or should it equal that of standard deviation ? For example, a dataset with standard deviation 1.915, and after applying linear regression has a RMSE value of 1.909 on the test set and after using Ridge regression it's RMSE is 1.826. Is this considered a good model or not?
I Would be grateful for your feedback.
Thank you. Regards
Thank you
even RMSE, MSE does not account for negative errors?
Thanks a lot, Nutshell description with example.
thank you so much !
nice sir ,,,, did u give any lecture in learning mall?
Thanks a lot 😊
Excellent video
At 1:15 how come the predicted values not on the best fit line? Doesn't it beat the whole purpose?
If there is no error, it indicates over fitting. Whole idea in a model evaluation is to identify the errors and reduce them to deliver optimal performance but most models will have some kind of errors.
IF a Regression Model said to be performing well using performance metrics MAE or MSE, then what will be the ranges of MAE or MSE when data is not scaled? What will be the ranges of MAE and MSE if the data scaled in between 0 and 1 or -1 to 1?
Values can range for 0 to infinity where lower value is preferred. Ideal value would be 0 indicating no error but that is practically not possible.
You are a God. Thank you!
Thank you so much for breaking down the differences. This helped so much.
Thank you Sir.
Thank you! Can you please check the link as it is not working
thanks, please check now. it is working
how do I know whether my data have outlier or not?
Simple explanation for outlier is that they are far away from the normal distribution for example if most values in your dataset are between 50-80 but one or few values are around 150. These values around 150 are your outliers. If you are using r or python, you can print summary of your dataset, that will give information about normal range and outliers
mast samjghaya hai
great
Thank you so much.
RMSLE typed wrongly at 6:57 min
6:40 RMSLE equation miss a right brace some where
Thanks for pointing that out, I will check.

MSE CAN NEVER BE NEGATIVE
